Pipe welding machines are increasingly used in the construction industry, and some large factories have introduced pipe welding machines: for example, square pipe welding machines and pipe welding machines with different functions. Now welded pipe equipment has become one of the indispensable equipment in welding plants. In terms of application, high-frequency pipe welding machines are mainly used...
Design and selection of fire dampers produced by fire damper production lines The smoke and fire dampers are now analyzed in combination with the specific ventilation system: the air supply fans in the underground garage should be equipped with electric air volume control valves or fire control valves (automatically closed at 70°C). If the air supply system needs to be shared with the fire-fightin...
The storage rack roll forming machine is used in the forming process of the storage shelf, and is mainly composed of an uncoiler, a straightening machine, a material limiter, a punching machine, a forming machine, a cutting device, an electric control panel and a beating table. It comes in a variety of sizes and usually weighs between 100 and 150 kg per layer. Can be used as a platform, easy to in...
There are four points that need to be paid attention to in the production process of automatic pipe welding machine: 1. First of all, the elongation of the pipe is longer than that of manual welding. Generally, 4-5mm is better. If it is too long, the penetration depth of the weld will be reduced, and the weld will not be beautiful; if it is too short, undercut and nozzle damage will occur. and oth...
The cut-to-length production line has high automation, fast processing speed and high-speed uncoiling. The leveling and shearing production line is used to uncoil, level and cut metal coils of different specifications into flat plates of required length and width. It has high processing precision and no scratch on the plate surface. It can process all kinds of metal sheets of all kinds of cold rol...
